shoes too big!! ideas please?

Dec 29 2011

hi, i bought shoes at the last minute today for a wedding that’s tomorrow, they are in my size and i cant take them back coz they were in the sales..(cant turn down a bargain) thing is there too big theres more grip and less slippage at the heel when i dont wear tights but im not comfortable unless i do and they slip really bad when im wearing tights. when im walking they slip up at the heel. i have bought heel grips and insoles but neither have helped at all. if anyone has any ideas of what else i could do please tell me.. im having a right panic. thanks
i forgot to mention there peep toes :/
